Illegal period structure. Date 06/04/2023 is in multiple periods in Fiscal Calendar. How to resolve?

AI generated answer (using internal Slack threads):

The error "Illegal period structure. Date 06/04/2023 is in multiple periods" is typically encountered when there is an overlap in the dates defined in different fiscal calendars. In NetSuite, the base period has to be consistent across all fiscal calendars. This means that a specific date can only belong to one period across all fiscal calendars. To resolve this issue, you need to ensure that the periods in your fiscal calendars do not overlap. If you have two fiscal calendars, one with 12 base periods (Calendar Months) and another with 13 base periods (4 week periods), you need to ensure that the start and end dates of these periods do not overlap. For example, if you have January in the Calendar Month Calendar starting on 01/01/2024, you cannot have Period 1 in the second calendar also starting on 01/01/2024. You would need to adjust the start and end dates of the periods in one of the calendars to ensure there is no overlap. If your company's fiscal structure requires overlapping periods, you may need to manually create your periods to fit your specific needs. This can be a tedious process, but it is necessary to avoid the "Illegal period structure" error.
